If only we could ask Omeluum for help.
"We desperately need a friendly mind flayer! If only there was a mind flayer around who owed me a pretty huge favor! And if only he were still in this city, just a few blocks away! And if only mind flayers like him were telepaths that could easily communicate with me from this distance because of the mind flayer larva that's eating my brain!"
This is another thing, like with
not being able to fix Karlach's engine even though you are given a very obvious signpost about how to do it and all the materials and personnel to do it are readily available
, where it's just baffling. Why would you go to all the trouble of orchestrating your plot to have an insoluble problem and then also go out of your way to put an obvious win-win solution literally right down the street? It's like if someone gave you the trolley problem but went out of their way to explain that the trolley's brakes are actually very effective and you could use them to stop the trolley from running over anyone, but they still only give you the two options where you run over people.
It's all the more frustrating because in most of their opportunities to make this mistake, they didn't! (Which isn't praise, because this should be an extremely easy mistake to not make.) In fact, they often did the opposite: allowing you to discover a win-win solution when it seemed like there wasn't one. (That is praise, because a game like this should reward player choice, player exploration, and build diversity.) In fact most of the companions seem built around just this exact narrative mechanism!
Shadowheart is bent on becoming a warrior monk for an evil god, Gale is committed to blowing himself up, Astarion is a prick who wants to become a turbo-vampire, Lae'zel is a xenophobic nationalist zealot obsessed with achieving something which will in fact be her doom, and Wyll is dead-set on killing Karlach. But better solutions can be found for all of them.
They involve some sacrifice, but you are allowed to find a better way by exploring the world around you and the world within your companions. But with
and not being able to ask Omeluum for help, the win-win solution is glaringly obviously signposted and seems to be telegraphed by the game itself, and yet you can't do it.
